I saw that page silverblade and that's what helped me get started. The 2nd and 3rd steps above use that method. The problem I'm having is when i try to combine them using a distribution map. That's what I'm trying to figure out. Sharon - It's not really a tut as It's flawed. If we can figure out what the problem is, then I suppose it could be a tut. :) I just don't want people confused thinking it's correct. Mazak - How the hell did you do that. You have two separate ecosystems forming a path. Did you have distribution maps on the individual ecosystems? If not, then how come that didnt' work for me. Post 6 above is that exact thing, but you can see the results are not correct. What's the difference between what you did and what I did? Thanks for all the help!! Dragontales
